Water soluble bag manufacturers manufacture a variety of custom and standard-duty bags for laundry, dry chemical, agro chemicals, and medical applications. They also produce bioplastic bags and reusable hygienic trash bags. Their products are manufactured using sustainable and renewable materials and are environmentally friendly. Their manufacturing capabilities include coating, printing, flexography, and hot stamping.

Water-soluble film is a powerful alternative to single-use plastics. It can be produced in a wide range of shapes and sizes and can be printed with colorful designs. Unlike traditional plastics, water-soluble film does not emit toxic fumes or break down into microplastics. It is also easy to recycle.

The composite film of the present invention is especially suited for laundry bags since the cold water soluble portion prevents stains from being transferred to the wash water. The wash water soluble portion is dissolved in the wash cycle and the remainder of the bag can be flushed away. This can make laundry more efficient by reducing wash times and improving sanitation.

Moreover, the hot water-soluble portion of the composite film is retained out of contact with the laundry and can be used to hold wet laundry or other items that cannot be placed in direct contact with the washer. The bag can be opened and emptied during the wash process. In some embodiments, the bags can be sealed so that the laundry is not in direct contact with the washing machine.

The bags may be formed from the composite film by employing essentially conventional bag forming techniques. The longitudinal ends of the film may be sealed by a heat seal or by an adhesive bond. In one embodiment, the composite film is folded around an additional hot water-soluble film to form a pouch and the edges of the film are adhesively bonded together to form a closed bag.

Another advantage of the hot water-soluble polybags is that they do not degrade into microplastics when disposed of in natural environments. This is because they dissolve in hot water and are naturally broken down by microorganisms into carbon dioxide and water as part of the natural cycle. This can be a significant advantage over the current use of disposable plastic bags in marine, lake, and river ecosystems, which are not readily broken down by microorganisms and can result in harmful toxins being released into these natural environments.

However, these benefits are countered by the fact that PVA polybags do not have a valid end-of-life strategy. Currently, most suggested disposal pathways involve running the bags under hot water or industrial composting them. However, this would require production of new plastics to replace the ones that have been discarded. Therefore, it is not clear that PVA polybags would represent a genuine solution to the problem of single-use plastics. Therefore, a large-scale switch to these bags would not significantly reduce the amount of plastic waste generated. A more realistic option might be to combine PVA bags with a system for converting them into a slurry that can be buried in landfills or reclaimed for industrial use.
